6bb2e34789 ARM: shmobile: Add koelsch defconfig
This is intended to be used until multi-arch is able to be
used for the koelsch board at which time a more generic configuration
will be used in place of this one.

This is based on the lager defconfig.

2457aaf73a ACPI and power management fixes for 3.12-rc2

     removed Device Tree parsing for CPU device nodes from cpufreq
     drivers from Sudeep KarkadaNagesha.
 
  2) Two fixes for recent cpufreq regressions introduced by changes
     related to the preservation of sysfs attributes over system
     suspend/resume cycles from Viresh Kumar.
 
  3) Fix for ACPI-based wakeup signaling in the PCI subsystem that
     fails to stop PME polling for devices put into the D3cold power
     state from Rafael J Wysocki.
 
  4) Fix for bad interactions between cpufreq and udev on systems
     supporting intel_pstate where acpi-cpufreq is available as well
     from Yinghai Lu.

509bf24d18 CacheFiles: Don't try to dump the index key if the cookie has been cleared
Don't try to dump the index key that distinguishes an object if netfs
data in the cookie the object refers to has been cleared (ie.  the
cookie has passed most of the way through
__fscache_relinquish_cookie()).

Since the netfs holds the index key, we can't get at it once the ->def
and ->netfs_data pointers have been cleared - and a NULL pointer
exception will ensue, usually just after a:

607566aecc CacheFiles: Fix memory leak in cachefiles_check_auxdata error paths
In cachefiles_check_auxdata(), we allocate auxbuf but fail to free it if
we determine there's an error or that the data is stale.

Further, assigning the output of vfs_getxattr() to auxbuf->len gives
problems with checking for errors as auxbuf->len is a u16.  We don't
actually need to set auxbuf->len, so keep the length in a variable for
now.  We shouldn't need to check the upper limit of the buffer as an
overflow there should be indicated by -ERANGE.

While we're at it, fscache_check_aux() returns an enum value, not an
int, so assign it to an appropriately typed variable rather than to ret.

87397fe10d slcan: rewrite of slc_bump and slc_encaps
The old implementation was heavy on str* functions and sprintf calls.
This version is more manual, but faster.

Profiling just the printing of a 3 char CAN-id resulted in 60 instructions
for the manual method and over 2000 for the sprintf method. Bear in
mind the profiling was done against libc and not the kernel sprintf.

Together with this rewrite an issue with sending and receiving of RTR frames
has been fixed by Oliver for the cases that the DLC is not zero.

cc9fa74e2a slip/slcan: added locking in wakeup function
The locking is needed, since the the internal buffer for the CAN frames is
changed during the wakeup call. This could cause buffer inconsistencies
under high loads, especially for the outgoing short CAN packet skbuffs.

The needed locks led to deadlocks before commit
"5ede52538e tty: Remove extra wakeup from pty
write() path", which removed the direct callback to the wakeup function from the
tty layer.

As slcan.c is based on slip.c the issue in the original code is fixed, too.

29cd718beb Bluetooth: don't release the port in rfcomm_dev_state_change()
When the dlc is closed, rfcomm_dev_state_change() tries to release the
port in the case it cannot get a reference to the tty. However this is
racy and not even needed.

Infact as Peter Hurley points out:

1. Only consider dlcs that are 'stolen' from a connected socket, ie.
   reused. Allocated dlcs cannot have been closed prior to port
   activate and so for these dlcs a tty reference will always be avail
   in rfcomm_dev_state_change() -- except for the conditions covered by
   #2b below.
2. If a tty was at some point previously created for this rfcomm, then
   either
   (a) the tty reference is still avail, so rfcomm_dev_state_change()
       will perform a hangup. So nothing to do, or,
   (b) the tty reference is no longer avail, and the tty_port will be
       destroyed by the last tty_port_put() in rfcomm_tty_cleanup.
       Again, no action required.
3. Prior to obtaining the dlc lock in rfcomm_dev_add(),
   rfcomm_dev_state_change() will not 'see' a rfcomm_dev so nothing to
   do here.
4. After releasing the dlc lock in rfcomm_dev_add(),
   rfcomm_dev_state_change() will 'see' an incomplete rfcomm_dev if a
   tty reference could not be obtained. Again, the best thing to do here
   is nothing. Any future attempted open() will block on
   rfcomm_dev_carrier_raised(). The unconnected device will exist until
   released by ioctl(RFCOMMRELEASEDEV).

The patch removes the aforementioned code and uses the
tty_port_tty_hangup() helper to hangup the tty.

df62cdf348 net_sched: htb: support of 64bit rates
HTB already can deal with 64bit rates, we only have to add two new
attributes so that tc can use them to break the current 32bit ABI
barrier.

TCA_HTB_RATE64 : class rate  (in bytes per second)
TCA_HTB_CEIL64 : class ceil  (in bytes per second)

This allows us to setup HTB on 40Gbps links, as 32bit limit is
actually ~34Gbps

3e1e3aae1f net_sched: add u64 rate to psched_ratecfg_precompute()
Add an extra u64 rate parameter to psched_ratecfg_precompute()
so that some qdisc can opt-in for 64bit rates in the future,
to overcome the ~34 Gbits limit.

psched_ratecfg_getrate() reports a legacy structure to
tc utility, so if actual rate is above the 32bit rate field,
cap it to the 34Gbit limit.
